Aluminum Frame FFU Clean Workbench Hepa Fan Filter Unit HEPA H14 Workshop For Laminar Flow Cleanroom

Technical Data

A Laminar Flow Clean Workbench (also known as a Laminar Flow Hood or Laminar Flow Bench) is a specialized workstation designed to provide a clean, particle-free environment for sensitive tasks that require high levels of air purity. It utilizes laminar airflow, which is a unidirectional flow of air that moves in parallel layers, with minimal turbulence, to reduce contamination in the work area.

Key Features of a Laminar Flow Clean Workbench:

1. Laminar Airflow:

   • The main characteristic of the laminar flow clean bench is the uniform, unidirectional airflow that filters the air and directs it in one direction, typically from top to bottom (vertical laminar flow) or from the back to the front (horizontal laminar flow).
   • The laminar flow ensures that any airborne contaminants (like dust or particles) are carried away from the work area, preventing them from settling on the surface of the items being worked on.

2. HEPA or ULPA Filtration:

   • The workbench is typically equipped with high-efficiency filters, such as HEPA (High-Efficiency Particulate Air) or ULPA (Ultra-Low Penetration Air) filters, which remove particles down to 0.3 microns (HEPA) or 0.12 microns (ULPA).
   • These filters ensure that the air entering the workspace is clean, minimizing the risk of contamination.

3. Clean Work Environment:

   • The clean bench creates a controlled environment with a low level of airborne particulate contamination, making it suitable for tasks like biosafety work, electronics assembly, pharmaceutical compounding, microbiological cultures, sterile packing, and other sensitive applications.

4. Work Surface:

   • The bench typically includes a stainless steel or other easy-to-clean surface, providing a clean and sterile work area for handling sensitive materials.
   • It may include accessories such as UV lights for sterilization or detailed controls for airflow and filter monitoring.

Types of Laminar Flow Workbenches:

1. Horizontal Laminar Flow Workbench:

   • Air is filtered and flows horizontally across the work surface, from the back of the unit to the front.
   • This type is commonly used for tasks where the user needs to work with objects placed on the workbench surface, ensuring that contaminants are swept away from the workspace.

2. Vertical Laminar Flow Workbench:

   • Air flows from the top downwards, creating a vertical air curtain that protects the workspace from airborne particles.
   • This type is often used for tasks involving larger objects or those that require more protection from contamination.

Applications:

• Microbiological Work: Culturing, handling biological samples, or preparing sterile environments for scientific experiments.
• Pharmaceuticals: In manufacturing or packaging sterile pharmaceutical products or compounds.
• Electronics Assembly: For assembly and testing of sensitive electronic components, where even minor contaminants can cause failures.
• Medical Devices: Used in the assembly and packaging of medical devices, ensuring that they are free from particles and microbial contamination.
